The man pulled a gun and said, "I'm going to kill everybody around here," according to family members.

They said he then shot his daughter, but his wife managed to escape.

The police arrived and started to close in on the house where the man was holed up. He then shot himself.

“I got a call that the daddy had killed the daughter, and so I rushed over here and from what I gather they were having a domestic dispute,” said family spokesman Reginald Wallace. “And they were married, and, ah, he said he was going to kill everything around him and he ended up killing the daughter, and he was barricaded in the house.”

Police have released a statement confirming what the family told WISN 12 News.
